Oxidative skeletal rearrangement of 5-aryl-4,5-dihydro-1,2,4-oxadiazoles into quinazolinones is induced by molecular oxygen (under a dry air atmosphere) that likely proceeds via transient iminyl radical species. Concise syntheses of biologically active quinazolinone derivatives were demonstrated using the present strategy.
5-芳基-4,5-二氢-1,2,4-恶二唑的氧化骨架重排成喹唑啉酮是由分子氧(在干燥的空气气氛下)诱导的,该分子氧可能是通过瞬态亚氨基自由基进行的。使用本策略证明了生物活性喹唑啉酮衍生物的简明合成。
